Something like an analogue of Sharepoint, how much will it cost?

Question

SharePoint

One of the offices wants to jump from SharePoint 2013.
I gently hint to them that this is not very realistic.
What do you think, even with reduced functionality, is it really possible to make an analogue of SP and how much will it be in person years?

Answer 1

I would say that this is not realistic even with a team of 10-20 people. Over 1,000 people have been working on the platform for 18 years now. You can make an analogue of one or two modules from the platform, but to make a complete analogue is a complete utopia without the capacity of both human and infrastructure. Offer them Bitrix

Answer 2

And how exactly is sharepoint used by you?
otherwise, like in the classic example, 'he starts photoshop just to remove the red eyes from the photos'
most importantly, how does the data get into sharepoint? How is mail collected, how do reports from accounting programs get there? can some converters set up so that tables from sql poured into reports beautifully? documents with a ball of an old babmoni working as a warehouse manager in the middle of nowhere were flooded, etc. What about group discussions? What about audio-video conferences? and voting and other collaboration?
even if you find something similar in functionality (and Google gives out a bunch of articles on this topic, including gsuite), setting up the entire integration can turn out to be a very serious task in itself, because it is unlikely that there will be some kind of automatic converter?
ps since Microsoft's pricing policy is payment by user, you can try to optimize the process by removing some users from access to the system, starting to write a layer for them, there are almost certainly a lot of people who need only one-way access (for reading and only their tasks) , transfer some of the tasks to third-party systems, step by step reducing the impact of the platform on the life of the company, and obviously this process has no guarantees of success and will be noticeably long, while it will require more than one person to implement I
